Mail service not accessible

My mail service is not accessible from the Internet, while it is working fine in LAN. Now I want to check from Internet where my mail serviced is blocked (my Upstream provides router inbound ACL or my firewall.)
Use a port-scanning tool like nmap to scan your IP address to check and see if TCP port 25 and 110 are open. These will need to be open to access your email from the Internet.
